How to Hire a Personal Injury Marketing Agency

A decision framework for PI firms - covering case-value economics, intake, signed-case measurement, and the spend levels required to compete.
By Josh Nelson, Editor-in-Chief9 min read

Personal injury is the highest-stakes category in legal marketing. Clicks on top intent terms run $100-$800 in competitive metros, the competition includes national firms and mass-tort advertisers spending seven figures a year, and the difference between a well-run and a badly-run program is not 20% - it is whether the program is profitable at all.

If you are evaluating law firm marketing companies for a PI practice, the general legal filters apply, and then these apply on top. Start with our broader guide on how to hire a law firm marketing company, then use the PI-specific tests below.

Filter 1: Do they optimize for case value or case count?

PI case values are wildly dispersed. Minor soft-tissue cases settle in the low five figures. Catastrophic injury, trucking, and wrongful death cases are worth orders of magnitude more. A program tuned for volume will fill your intake with low-value claims and look great in a dashboard.

A specialist agency talks about case mix:

  • Separate campaign structures and bid levels for high-value case types (trucking, catastrophic injury, wrongful death, premises with clear liability) versus volume case types (minor MVA, slip and fall).
  • Negative keyword discipline that removes claimant-adverse and low-value intent - insurance-defense queries, "how much is my claim worth" browsers, do-it-yourself claim searchers, and existing-client service terms.
  • Willingness to say a case type is not worth bidding on in your market.

Ask: "What was the average case value by source for your PI clients last year, and how did you shift spend based on it?" A specialist has the answer and the story behind it. A generalist pivots to cost per lead.

Filter 2: Intake, or the whole thing leaks

In PI, most wasted marketing spend is not wasted on clicks. It is wasted between the call and the signed retainer. Industry-typical patterns worth checking in your own numbers:

  • A large share of calls to PI firms go unanswered or to voicemail outside business hours - and injured claimants call the next firm immediately.
  • Speed to first contact is the single strongest predictor of signing a case.
  • Follow-up on unsigned but qualified leads is usually abandoned after one or two attempts.

The agency does not have to run your intake, but they must be accountable to it. What good looks like:

  • Call recordings reviewed with you monthly, with specific intake coaching notes.
  • Reporting on answer rate, average speed to answer, and after-hours handling.
  • Integration with Clio Grow, Lawmatics, Litify, Captorra, or your case management system so leads are tracked to signed retainers.
  • A defined nurture sequence for qualified-but-unsigned leads.

An agency that shrugs at intake is selling you a leaky bucket and blaming the water.

Filter 3: The channel stack, and what it costs to compete

  1. Google Ads search. The core of most PI programs and the most expensive. Requires daily-level management, aggressive negatives, geo and schedule weighting, and separate structure by case type.
  2. Local Services Ads where available for legal categories - typically cheaper per lead than search, with tighter screening.
  3. Local SEO and Google Business Profile. Practice area plus city queries, review velocity, and map-pack visibility. Slow and durable.
  4. Practice-area SEO and case-result content. The compounding asset that lowers blended cost per case over years, not months.
  5. YouTube and Meta for brand. Real in competitive metros - name recognition lifts search conversion rates measurably. Not a first program.
  6. Referral and co-counsel relationships. Still the highest-margin case source in PI. Marketing should support it, not replace it.

Realistic fee levels in 2026: $5,000-$12,000/month for a small firm running local SEO and a focused paid program; $10,000-$30,000/month for a mid-size firm with a meaningful paid budget; $30,000-$100,000+/month for competitive-metro multi-channel programs including video. Media spend is separate and must be billed to accounts the firm owns.

If your total available spend is under roughly $5,000 per month in a top-50 metro, do not start with broad paid search on car accident terms. Start with Google Business Profile, reviews, LSA, and a narrow set of long-tail case-type pages.

Filter 4: Compliance, ethics, and the disclaimers

State bar advertising rules are not a formality. Restrictions commonly cover terms like "specialist" and "expert", past-result claims, client testimonials, simulated depictions, and required disclaimers on ads and landing pages. Non-compliant creative creates bar exposure for the firm, not the agency.

What to require:

  • The agency names the specific rules in your state that will constrain copy, in the first two calls.
  • A documented compliance review step before anything publishes, with a partner sign-off path.
  • Case-result content that carries proper disclaimers by default.
  • No volume promises that make review impossible.

Filter 5: Reporting that a managing partner can act on

The scoreboard is signed cases and case value, not leads:

  • Cost per signed case, by source and by case type.
  • Signed cases by source, month over month.
  • Intake qualification rate by source.
  • Average and median case value by source.
  • Impression share and CPC trend on top intent terms.
  • Map pack and organic visibility for practice area plus city.

Everything else is diagnostic detail.

When not to hire an agency yet

  1. Intake cannot answer calls 24/7. Fix that first, in-house or with an answering service. It is cheaper than any campaign.
  2. You cannot handle more case volume. PI throughput is attorney and paralegal capacity. Scale the team before the spend.
  3. You have no case management system. Without it, nobody can measure cost per signed case, and you will be flying blind.
  4. Your total marketing budget is below the market's entry cost. In hyper-competitive metros, an underfunded paid program loses to firms spending ten times more. Start with organic, reviews, and referral channels.

The short version:

  • Optimize for case value and case mix, not lead volume.
  • Intake is the biggest lever in PI marketing. Hold the agency accountable to it.
  • Expect $5K-$30K/month in fees for most firms, more in competitive metros, with media separate.
  • Bar compliance review must be a documented step, not an afterthought.
  • Demand cost per signed case by source and case type.
